I don't think so, we know he has seen Hal in the RAH backstage and also at the Illsley's book presentation, that he helped JAck raising money when his daughter died, but the rest, I don't think he would want to contact them, specially Chris and Alan since they started "The Straits" and the keep it with their bands "DS Experience" and "DS Legacy"...
I think that working with any of them would be more a dream than a reality, but, who knows...
